This reportextensively details four of those mission areas (national missile defense having beencovered in great detail elsewhere). The authors define homeland security and its missionareas, provide a methodology for assessing homeland security response options, and reviewrelevant trend data for each mission area. They also assess the adequacy of the doctrine,organizations, training, leadership, materiel, and soldier systems and provide illustrativescenarios to help clarify Army planning priorities. The report concludes with options andrecommendations for developing more cost-effective programs and recommends a planningframework that can facilitate planning to meet homeland security needs.
